摘要

摘要新热带部落Sphaenorhynchini包括15个公认的物种，其中14个属于Sphaenorhynchus属，1个属于Gabohyla属。在这里，我们重新描述了幼虫的外部形态，并包括关于G.pauloalvini和S.prasinus侧线系统的新信息。此外，我们还对保氏锥虫的产卵地点和幼虫发育进行了评论。G.pauloalvini的蝌蚪与所有描述的Sphanorhynchus幼虫的区别在于，它们在颜色上有一个独特的条纹组合：身体上有三个侧面的深色条纹（角、斜和腹外侧），尾部有一个单独的腹侧深色条纹。prasinus的蝌蚪与G.pauloalvini的蝌蚪以及Sphaenorhynchus的所有其他幼虫的区别在于，它们的尾部肌肉组织上有一条单一的中间深色条纹，以及其他特征。保氏小蝌蚪和普氏小蝌蚪是游泳的，它们在水柱中央或池塘深处游泳。观察到保罗尔维尼的成虫坐在幼仔旁边，这加强了该物种由父母照顾的可能性。

Redescription of the Tadpoles of Gabohyla pauloalvini (Bokermann, 1973) and Sphaenorhynchus prasinus (Bokermann, 1973) (Hylidae: Sphaenorhynchini)

Abstract. The Neotropical tribe Sphaenorhynchini includes 15 recognized species, 14 of which are allocated to the genus Sphaenorhynchus and 1 in the genus Gabohyla. Here, we redescribe the external larval morphology and include novel information on the lateral line system of G. pauloalvini and S. prasinus from the type localities. In addition, we include comments on the oviposition site and larval development of G. pauloalvini. The tadpoles of G. pauloalvini differentiate from all described larvae of Sphaenorhynchus by having a unique combination of stripes in the coloration: three lateral dark stripes (canthal, oblique, and ventrolateral) on the body and a single ventral dark stripe on the tail. The tadpoles of S. prasinus distinguish from those of G. pauloalvini and from all other larvae of Sphaenorhynchus by having a single, median, dark stripe on the tail musculature, among other characters. Tadpoles of G. pauloalvini and S. prasinus are nektonic and found swimming in the middle of the water column or in deeper regions of ponds. Adults of G. pauloalvini were observed sitting next to spawns, reinforcing the possibility of parental care in this species.

期刊介绍： The Journal of Herpetology accepts manuscripts on all aspects on the biology of amphibians and reptiles including their behavior, conservation, ecology, morphology, physiology, and systematics, as well as herpetological education. We encourage authors to submit manuscripts that are data-driven and rigorous tests of hypotheses, or provide thorough descriptions of novel taxa (living or fossil). Topics may address theoretical issues in a thoughtful, quantitative way. Reviews and policy papers that provide new insight on the herpetological sciences are also welcome, but they must be more than simple literature reviews. These papers must have a central focus that propose a new argument for understanding a concept or a new approach for answering a question or solving a problem. Focus sections that combine papers on related topics are normally determined by the Editors. Publication in the Long-Term Perspectives section is by invitation only. Papers on captive breeding, new techniques or sampling methods, anecdotal or isolated natural history observations, geographic range extensions, and essays should be submitted to our sister journal, Herpetological Review.
